FINGERRI'NG. METHOD OF'MAKING IT Jacob Karlan, New York, N. Y. AppucanbnSeptember 26, rest;shame-102x16 3 Claims.

My invention relates to a two-piece finger ring, in which the annulus ismade fromja blank, and the new feature is the formation of the sidepieces for the crown of the ring from the blank of the annulus.

A further featureof my invention isthe method of fabricating the ringannulus. I

An object of the invention is to provide a stamped ring in which theannulus shaped from a'blank has, as an integral part thereof, box sidesextending from the side of the blank of the annulus and side piecesraised from the body of the blank. of the annulus in proximity of thebox sides.

In the two-piece ring" made hitherto, there is an annulus blank anda'crown blank. The crown blank forms the top -and'the side pieces, whereasin my ring'the side pieces and the box for the jewel top are formed fromthe blank for the annulus.

' By providing a ring having a top without side pieces, I permit ajeweler to have a selection of tops for different sizes of gems orstories to fit the'sameannulus. By forming the side pieces 5 from theblank of the annulus, I reduce the amount of soldering since the onlypart to be soldered in my'ring' is the top,- whereas in the two-piecering hitherto made, the side pieces as I well as the top which form theunit hadto be 30 soldered to the annulus-ofthe ring in the asseniblirig;

Another advantage of my ring is that it permits the jeweler theselection of any desired top for the same annulus, without the necessityof 5 using independent side pieces in conjunction with a top for a largesize jewel or stone.

It may be remarked that in my ring, by forming the side pieces from theblank of the annulus, I in reality form the crown of the ring, with the40 exception of the top, from the blank of the annulus, thus providing aselectivity of decorations and jewels of various sizes with suitabletops for the annulus, without any change or additional.

labor on the annulus. 45 In the appended drawing forming part of thisapplication,

Figure 1 is an elevation of a ring embodying my invention.

Figure 2 is a vertical section through the plane 50 of the ring on theline '2-2, Figure 3, showing a slight modification of the ring.

Figure 3 is a top View of the ring in Figure 2, a portion of the topbeing removed to show the box formation of the ring to which the top is55 secured.

Referring to the drawing, IU-is'the ring a'nnu- 1o lus formed of a blankI l. The blank is provided" with side or lateral wings t2 at its-centralfiat tenedpart l3: To each side of the central part [3 in the body ofthe blank H, thickened portions l4 are provided from which any desired15 design may be formed by swedging, drawing or stamping.

Asshown in Figure 4, the blank is" stamped with a d'esign'suitable forthe type of ring being made.

The portion of the blank I] at I4 is hollowed 20- out on the innersurface which is to'form the concavesur'face of the annulus (see Figures2, 5 and6)', or it may be left solid as shown in Figure 1. Afterstamping the blank is trimmed of surplus metal. 7

As shown in Figures 2, 5 and fi the'thickened portions id have beendrawn in forming the decoration-thereon, thus providing a hollow I5 onthe under or concave surface of the blank. This hollow isspanned'tran'sversely by the central part I 3. This spanning portionof'the' blank provides lateral rigidity thereat. Whether these portionsM are drawn or swedged, they will present above the spanning centralportion I3, spaced raised edges 22. These raised portions l4 constitutethe side pieces of the crown of the ring. Whether these side pieces aremade solid, as shown in Figure. 1, or hollow, as shown in Figure 2, theyare then slitted parallel to the plane of the blank, to permit thesevered portion or top 23 of side pieces 40 M to move from the body ofthe blank when shaping the blank into an annulus. The slitting may be onstraight lines or dented to give the desired configuration to the sidewalls of the side pieces l4 and to the annulus thereat.

It is evident that the top 23 of each side piece l4 at the end remotefrom the central part l3 forms an integral part of the blank, althoughthe top 23 is separated from the blank body as it nears the central partl3, the separation or angular clearance therebetween increasing as theyapproach the central part l3 of the blank when it is shaped into anannulus.

The slitting accomplishes two functions: It permits giving the annulusof the ring a lateral design on the side walls of the side pieces l4 andpermits the slitted part to move relatively to the blank body when it isshaped into an annulus, in addition it gives the appearance of a heaviertype of ring at the crown with a minimum of metal.

After the side pieces l4 have been raised from the body of the blank thewings I2 are shaped (see upper part of Figure 7) to form a centralportion l1 and side portions 18. The side portions are then bent towardthe central part I1 into the same direction as the side pieces 23 wereraised from the blank (see the lower part ,of Figure '7) so that eachsection of the box formed is of channelled cross-section, the channelledside of the box section being on the inside of the box, as best seen inFigure 3.

After the desired design has been formed in the Wings and the blank, thewings are bent on the junction line H! of the wings with the blank toform the box sections or sides 20, as best seen 7 in Figure 3.

It will be noted that the side portions 18 forming the channel of thebox section, will approach the edges of the raised side pieces 14, butthere will be a clearance between them; see Figure 3.

To prevent the raised side pieces M from being bent accidentally towardthe blank, I provide prongs 2| on the side portions l8 of the wings, asbest indicated in Figure '7, which prongs 2| will come under theadjacent edge of the side pieces l4 and form a support therefor.In-cases where the side pieces M of the blank are brought to the levelof the top of the formed box 26, they may be soldered to the top whenthe top is soldered to the box, and thus omit the prongs 2!.

It will be seen that in my construction the box is formed from twospaced channelled sections formed integrally from lateral pieces orwings of I the annulus blank, and that each of said channelled boxportions has its depth of channel increasing as it rises from the blank,and although said box sections extend toward the raised side pieces,they are not connected therewith except in forming a support so that theraised side pieces may not be depressed accidentallyror otherwise.

The so-formed blank, when shaped into an annulus as indicated in Figures1 to 3 inclusive,

has a gap 2 3 which may be soldered when the.

ring is finished. The top 25, to be fitted to the shaped box 20 is inconformity to said shape and of a type common in ring findings foraccommodating a jewel or a stone. As shown in the drawing, it isrectangular in configuration, provided with a central opening properlyflared to accommodate a jewel or stone.

From the description, it will be seen that when the annulus is shaped,the only thing necessary to complete the ring is the top, so that in myring formed of two pieces, the main piece formed of the annulus blank isprovided with everything except the gem or stone carrying top. Thus, Iprovide a ring in two parts which diflers from the two-piece ringshitherto made, in that my top is without side pieces. The side pieces inmy ring are raised from and integral with the blank from which theannulus is formed, and so is the box which carries the stop. The blankat the box between the side pieces spans the box at the bottom thereofand'provides lateral rigidity for the annulus and box thereat.

I claim:

a 1. In a finger ring, an annulus formed from a blank having hollowedout spaced side pieces raised from the body of the blank and lateral boxsections of channelled cross-section formed from the body of the blankabout the space of said side pieces, said blank having an integralportion thereof at the spaced side pieces extending between theboxsections and lying inthe inner V annular area of the annulus, and a topsecured to saidbox sections.

2. A method of making fingerrings which comprises stam'ping a blank topresent a central portion with side wings thereat and a raised bodyportion in the blank to each side of the central portion, slitting theraised portions of the blank in a plane parallel to the plane of theblank, shaping and bendingthe wings toward the raised portions to form abox thereat, and bending'the blank into an annulus.

3. A method of making finger rings which comprisesforming a blankpresenting a central portion with side wings thereat and a raised bodyportion in the blank to each side of the central portion, slitting eachraised portion of the blank parallel to the plane of the blank at thecentral part thereof, shaping and bending the wings into channelledsections and bending them toward the flattened central part to form abox, and bending the blank into an annulus.
